Abstract
The invention relates to a method for manufacturing a cold-rolled galvanizing sheet metal strip and equipment for manufacturing, the strip is started from the hot-rolled strip, the strip is firstly washed with acid, which is further cold rolled and galvanized, when a rolled strip (2) is continuously washed by acid, cold rolled and galvanized on a continuous production chain (1) in turn, forged strips can be quickly produced with low cost.
Description
The present invention relates to a kind of utilization independently or with pickler bonded cold-rolling mill, produce the method and apparatus of the band of cold rolling, galvanized, pickling by the prefabricated band of hot rolling, this method and equipment also are used for the cold-strip of hot galvanizing apparatus is annealed and plating, the prefabricated band of described hot rolling begins earlier through overpickling, then accept cold rollingly, accept zinc-plated processing subsequently.
In the prior art, well-known is on a pickling lines the prefabricated band of hot rolling to be carried out pickling in order to produce the cold-rolling galvanization band.On the one hand, described pickling operation is used for removing the oxide skin that produces in hot rolling; On the other hand, described pickling operation is used to remove the oxide skin that is gathered on the band.Subsequently, in cold-rolling mill, depressed desirable to obtain, common finished product thickness less than 1mm through the hot rolled band of overpickling.After cold-rolled process, the band that is rolled into the roll coil of strip is accepted anneal and as the zinc-plated processing of acceptance in a hot galvanizing apparatus.
Normally multistep is rapid realizes for such band treating processes.This means, at first, with the pickler coupling or independently be rolled down to finished product thickness the hot rolled band pickling and hot rolled band in the cold-rolling mill.At this moment, cold-strip is rolled into the roll coil of strip as mentioned above and by delivering in the hot galvanizing apparatus a long way off as crane, ground fortune volume vehicle or air-cushion type delivery system, anneals and zinc-plated processing so that accept there.
Such processing mode is very unfavorable to the throughput of cold-rolling galvanization band, and this mainly is because the time-consuming roll coil of strip carrying between cold-rolling mill and galvanizing rig.In addition, roll coil of strip carrying needs extra personnel, so the total production cost of high-quality cold-strip obviously improves.Cause its sales force in steel with keen competition are loud, obviously to reduce thus.
The objective of the invention is to improve above-mentioned the sort of method and apparatus, thus can be fast and the band of production high-quality at low cost.
According to the present invention, above-mentioned purpose is so to realize, promptly rolled strip is successively accepted pickling, cold rolling and zinc-plated processing continuously on a tinuous production.Owing on a tinuous production, advantageously cold-rolled process and acid cleaning process and galvanizing process are linked together, carry thereby eliminated so far between cold-rolling mill and galvanizing rig required, the time-consuming and expensive roll coil of strip.Improve the throughput of whole production equipment on the one hand thus, and also reduced personnel requirement on the other hand.In addition, obviously reduced the required cost of investment of production line of the present invention by saving roll coil of strip handling processing.
Generally speaking, above-mentioned advantage obviously reduces the production cost of fine cold-strip per ton.
Be to realize technology of the present invention, the present invention has stipulated: be provided with at least one and depress frame between the pickling section of production unit and zinc-plated section.Depress in the frame at this, utilize one to depress the and then cold rolling finished product thickness that is pressed down to of rolled strip that passage will be come out from pickle solution.But also it is contemplated that out, adopted many follow-up cold rolling frames for the heavy reduction that obtains thickness of strip.
Other advantage and characteristics will provide in claims He in the following description book, will further describe an embodiment shown in the drawings in the following description book.
In unique accompanying drawing, schematically drawn one and be used for rolled strip 2 is carried out the band production line 1 of the continous way running of pickling, cold rolling and zinc-plated processing.
Band production line 1 have 3, one reeling machines 4 of an input section in this input section to carrying out uncoiling through hot rolling and the rolled strip 2 that is rolled into the roll coil of strip in advance.In addition, input section 3 is furnished with one at this unshowned band welding plant.The band welding plant has been guaranteed the favourable band of technology is advanced continuously, and this is because the single roll coil of strip is welded into a band for no reason.
After input section 3 is a pickling section 5, and rolled strip 2 is for example accepted the electrolytic pickling processing or utilized acidic fluid to carry out pickling in this pickling section, so that remove the oxide skin that produces in hot rolling.Subsequently, through the rolled strip 2 of overpickling directly given depress frame 6 and sweep under the pressurized rolling so that obtain desirable finished product thickness.
After cold-rolled process, rolled strip 2 is through a washing unit 7, the oxide film of removing rolling emulsion or ROLLING OIL and caused by pickling in this washing unit.Cause the good set situation of zinc layer thus, described zinc layer is for example to be plated on the rolled strip with hot dip process mode or electrolysis mode in subsequently zinc-plated section 8.
Then, just 2 through a finishing frame 9, described band is accepted the temper rolling processing in this finishing frame through the zinc-plated and rolling band that is subjected to corrosionproof protection thus.One is connected tension flattening machine 10 finishing frame 9 back, that be used with finishing frame 9 and has eliminated by Flatness deviation such as the thick partially phenomenon of limit wave or rolled strip center rolling and that annealing causes.
At last, utilize a reeling machine 12 that is arranged in the deferent segment 11 of band production line 1 that high-quality rolled strip 2 is rolled into the roll coil of strip.
Claims (2)
1. method of producing the cold-rolling galvanization sheet metal strip by the hot rolling band, described band is accepted cleanup acid treatment earlier, accept cold rolling then, accept zinc-plated processing subsequently, it is characterized in that, rolled strip (2) is successively accepted pickling, cold rolling and zinc-plated processing continuously on a tinuous production (1).
2. the production unit through the cold-rolling galvanization sheet metal strip of overpickling is characterized in that, is provided with at least one and depresses frame (6) between pickling section (5) and zinc-plated section (8).
